Abstract
A deflectable catheter includes a catheter body, an intermediate section, a tip electrode and a control handle for deflecting the catheter by manipulation of a puller element that is made of a high modulus fiber material and extends through the catheter body and the intermediate section. The proximal end of the puller element is housed in the control handle and the distal end of the puller element is in a wrapped configuration and engages with a distal tip member or the intermediate section.
Claims25
A deflectable catheter comprising:
- a catheter body;
- an intermediate section at a distal end of the catheter body;
- a distal tip electrode distal the intermediate section, the distal tip electrode comprising an electrode main body and an electrode stem at a proximal end of the electrode main body;
- a control handle at a proximal end of the catheter body;
- and
- a puller element having proximal and distal ends, the puller element extending through the catheter body and the intermediate section, wherein the proximal end of the puller element is housed in the control handle and the distal end of the puller element is anchored in a wrapped configuration to at least a portion of an outer circumferential wall of the stem of the distal tip electrode, and manipulation of the control handle results in movement of the puller element to deflect the intermediate section.
A deflectable catheter comprising:
- a catheter body;
- an intermediate section at a distal end of the catheter body;
- a control handle at a proximal end of the catheter body;
- and
- a puller element having proximal and distal ends, the puller element extending through the catheter body and the intermediate section, wherein the proximal end of the puller element is housed in the control handle and the distal end of the puller element is in engagement with a loop attached to an interior side wall of the intermediate section, and manipulation of the control handle results in movement of the puller element to deflect the intermediate section.
A deflectable catheter comprising:
- a catheter body having proximal and distal ends;
- an intermediate section distal the catheter body;
- a distal tip electrode distal the intermediate section, the distal tip electrode comprising an electrode main body and an electrode stem at a proximal end of the electrode main body;
- a puller element having proximal and distal ends, the puller element extending through the catheter body and the intermediate section, wherein the puller element is anchored in a wrapped configuration to at least a portion of an outer circumferential wall of the stem of the distal tip electrode.
